The present invention relates to aradioactive means for activating Water, espec allytable waters, in bottles. On account of the ex- .pensiveness of the radioactive preparations it is of the greatest importance, when they are intended to be used for the activation of mineral waters to make provisions for preventing the loss of the radio-active preparations which are capableto preserve their full activity for a very long time. When the radio-activation of the water has to be carried out in the bottles, or in other words when the radio-active substance has to be inserted into the bottle-this being advisable especially for the reason that thereby the high radio-activity of the water at the moment when it has to be used is best ensuredthere exists the danger,cthat the radio-active substance drops out of the bottle when the water i is being poured out. This danger exists also when the radio-active substance is enclosed in a small envelope or capsule of porous mateof the liquid and clog the bottle neck.

Radioactive substance fixed on the bottom, on the inner surface of the bottle or other vessel cannot be totally surrounded by the water so that the substance is not completely utilized. Moreover the fixed connection of the radio-active substance with the --vessel requires a complicated and therefore expensive construction. WVhen the vessel is broken, the radio-active substance will be destroyed generally. It is further difficult and sometimes impossible to remove the radio-actlve mass from the vessel for repalr or renewal or when the vessel has tobe cleaned.

All these inconveniences are avoided by the present invention. According to the invention the insoluble radio-active mass is encircled by aresilient or elastic spreadable body, which allows the insertion into and the intentional removing from the bottle, but prevents accidental dropping out when the water or the like is being poured out, clogging of the bottle neck, or resting of the radio-active mass directly on the bottom or on the wall of I the bottle. This resilient or elastic-bodymay be constructed in difierent manners. "Itfmay; for instance, consist of an envelope or sleeve I of small size .encloslng the radio-act ve mass,

and having resilient arms extending "in "different' directions. Or it is formedby elastic trellis work whichencloses the radio-active mass and is of such size that it can be inserted or removed through the bottleneck only when the elastic trellis work has been compressed. In this case the elastic spreadable body has the shape of a small elastic cage in which the radio-active; mass is arranged directly or indirectly.

cage 0. The cage 0 is formed by rods d which, as shown in Figs. 1 and 2, are bent" outwards at the middle portion and joined at. theends. The upper andlower ends of the 05 .Two embodiments of'the invention are ilrv rods or wires 0? are fixed to plates 6 by soldering orin any other convenient manner. the curving of the cage 0 at the middle a cer-j tain elasticity is obtained so that the cage can be forced through a bottle neckthe'inner diameter of which is slightly smaller than the accordingly in order. to fulfill the object. When the cage has been inserted into'the bottle it; cannot dropout when the water is being poured out or when the bottle is'turned upside down. As the water can freely*flow through the cageit is impossible that the bottle neckbe clogged, even when the cage greatest diameter of the cage at the mid'dle'of 9 7 the wires 03. This greatest diameter atthe middle of the. cage must therefore be selected 1 everal cage-at the same time prevents the radioactive substance from resting directly upon the bottom or wall of the bottle or other ves sel, this being essential for the thorough utilizationof the radio-active substance. i f In the formofconstruction shown in Fig.

The wiresor rods Ofthfi small cage (Figs. 1 to 3)may be di- Vrectly united by soldering insteadof being fixed to the plates, orthey might be united by small caps which may befixed 'by soldering or the like. The wires or rods may also be arranged in such a manner thatthey are narrowly joined only atone end of thecage whereas the bulged out part is arranged: at

this easethe point, which opposes resistance against accidental dropping-outof the cage from the bottle, will then .be the correspondingendof the cage and notthe middle, this end being elastic to permit corres ondingv com ression for removal of the cage min the bott e. The cage for the radio-active sub stance might further bemade from elastic.
